You claim that "[fusion] leaves no nasty reminants[sic]". I'm not sure what you mean. Obviously, the reactor parts will be bombarded with high energy neutrons for the duration of its service life. Tons of radioactive cement and steel sure sounds like nasty remnants to me...

Solar cells are a type of semiconductor. And we all know how clean and pollution free the semiconductor manufacturing industry is. Pollution free, hah!
As I recall, the law made it illegal to manufacture or import radios that could receive analog cellular or could be readily modified to. I believe it's rather trivial to import a inblocked scanner from, say Europe. Of course, the real fun starts when you modify a dual band amateur radio tranciever to transmit on the cellular band so you can interject your own comments...
Apparently the kit has changed a bit over the years (not surprising). When I competed in 95 and 96 there was no software. The controller was literally a black box with terminals to hook up the motors and a few jumpers to configure limit switches and such.
No electronics, no software. You'd better be a mechanical engineer, welder, or machinist if you want to participate. All the interesting parts are handed to you in a little plastic box. Budding EEs will have to be content with relays and limit switches. At least that was the story when I competed 5 or 6 years ago.

Even that's not correct. Electrons in copper move very slowly, on the order of centimeters/minute. Ripples, on the other hand travel at approximately half c (or thereabouts).

Here's my own image compressor. It's just like jpeg but I had to trim the source a bit to fit inside the teeny-tiny submission box. I hope you can still understand it.
The codec emits a byte stream considerably larger than the raw image (4x) but this stream is easily compressed by bzip2 or gzip. It reads and writes portable gray map (.pgm) files (both ascii and binary). If you want color I suggest you transform the image into YUV colorspace and compress each plane seperately. The color planes should be downsampled 4:1 (2x2 blocks) and compressed at very low quality (less than 15).

But the earth isn't a closed system, we have continuous energy input from the sun. We could use solar energy to extract and concentrate the dispersed platinum. Theoretically, we could just make platinum directly from solar energy if we wanted.

Titanium is quite reactive and quickly forms a protective oxide film when exposed to oxygen. The oxide film doesn't flake off (unlike iron oxide) and protects the metal from further damage. Aluminum, another very reactive metal, does the same thing.

To make a pgm from a jpeg use:
djpeg -grayscale -pnm image.jpg > image.pgm
Hints:
Try quality settings from 15 to 200.
Bad input causes core dumps.
The image is cropped if the dimensions aren't divisible by 8.

You have to multiply the percentages. Since x is commonly used as a variable, we use a dot instead.
Therefore, 99% and 98% = 99.98%
